@Oneanne I was going to say that the Dolphin ought to be lovely - but now I guess you will be just as happy at Pop!! Did they already have the renovated rooms when you stayed there last time? They do look nice, but a bit bland. If you are looking into ways to do fun tours at WDW, the two that I am currently thinking of is the cake decorating class at Amorette's - you get to keep the cake, maybe not the best thing to do on a solo trip... And the other one is the tour at Epcot where you get to snorkel with the fishies at the Sea pavilion in Epcot. Wild Africa Trek is great, too, though. They also have a new tour there that gets high marks that is called "Caring for giants" and it is about the elephants at AK.
Yes, I've heard about Caring for Giants but couldn't do it last trip because we had group stuff planned for the day it was offered while I was there. I've done the tour of Future World but not World Showcase, so that's a possibility. I didn't stay in a renovated room last trip, but think it might be nice to have the second bed up and out of the way.
